Brand new DBX 252.3 sub box.

The DBXs are sub boxes designed to enhance the audio system performance in the low range frequencies, optimizing the spaces and ensuring a quick, not too invasive installation. The dual 10″” (250mm) subwoofer unit, which is the DS sub, provides unmatched SPL output and superior power handling. The Fine-tuned sealed enclosure, developed through computer aided simulations and refined with in-car listening sessions ensure a ready-to-sound performance. The rear slanted panel fulfils two important functions: it reduces back-wave reflections and eases the installation.
